What was true about one-drop rule?

The one-drop rule is a social and legal principle of racial classification that was historically prominent in the United States in the 20th century. It asserted that any person with even one ancestor of black ancestry ("one drop" of black blood)[1][2] is considered black (Negro or colored in historical terms).

This concept became codified into the law of some states in the early 20th century. It was associated with the principle of "invisible blackness" that developed after the long history of racial interaction in the South, which had included the hardening of slavery as a racial caste and later segregation. It is an example of hypodescent, the automatic assignment of children of a mixed union between different socioeconomic or ethnic groups to the group with the lower status, regardless of proportion of ancestry in different groups.[3]

The one-drop rule is defunct in law in the United States and was never codified into federal law.
